• Resumen

  • Briefly restricting blood flow to a person's arm seems to prime the heart and other organs to cope with a more severe loss of their blood supply. The technique could improve recovery from surgery, a heart attack or stroke. The effect relies on a phenomenon called ischemic conditioning, first seen in animal experiments that temporarily cut off the heart's blood supply. Researchers found that there was less damage to the heart if its blood supply was briefly lowered beforehand. It was as if the heart muscle had been trained to withstand oxygen deprivation.
